Frustrating

Kate lay awake in bed desperately trying to ignore the itch between her legs but it was a losing battle and after a little while she reached into her night stand pulling out a dildo, unfortunately no matter how much she tried the dildo just couldn't satisfy her like Lara did, suddenly realising how bad it was to think of her daughter as a sexual aid Kate felt nothing but shame and buried her face in her hands, after a few more hours failing to cum she finally fell asleep.

The next few days played out pretty much the same until one day when Abby had taken Tara to daycare and left for her job, Kate was in the kitchen making breakfast when Lara came down and after taking one look at her mother she said "another rough night", "well you don't look much better" Kate said pointing to the bags under Lara's eyes, "it was a pretty long night for me" Lara said walking over to the kitchen counter "is Abby out?", "yes she took Tara and wont be back until tonight" Kate replied moving around to stand right in front of Lara, "so we are alone for the whole day" Lara said moving a little closer, suddenly Kate dropped to her knees "please i need release" she practically screamed while pawing at her daughter's legs.

In a reversal of roles Lara gave some orders then told her mother to strip off and lie on the floor, she then turned into pair of bondage underwear which included built in dildos for both her pussy and ass, lining up the dildos she inserted them slowly with the first going in her pussy, the head of which was very large but eventually it entered with a bit of **** causing her to yelp out loud, as she continued to insert it the anal dildo pressed on her ass, this one was much smaller but was harder to take given her lack of experience with anal, once it was in she pulled the underwear all the way up and not a second later they started to vibrate, if she had been thinking clearly Kate would have realised why Lara told her to get on the floor, her legs had turned to jelly from the first orgasm and she was flopping around like a fish as all the pent up frustration she had been building was released all at once, Lara was now very glad she had chosen to be made of rubber as her mom was squirting all over her and the floor.

After the first five or six orgasms Kate had began to compose herself a little so she started on the tasks Lara had given her, even getting to her feet was a struggle as the next orgasm was building so she didn't know if she would be able to....
